Found this and wow this is a good read.

As a pilot and aviation enthusiast, the first sentence killed it. The correct trim for the P-40B is 5 degrees rudder trim to the right, 0 degrees for aileron and elevator trim.... Even in a Cessna 152 or 172, a Boeing 747, or whatever else you can think of, none of them use full anything trim for takeoff. Also, the old warbirds rarely used full throttle for takeoff as it could result in engine or prop damage at low airspeeds among other reasons. The slow, smooth application of power was a must, otherwise the engine could over rev or ground loop. The propeller control (RPM control) on Curtis P-40 was rudimentary compared to today's electric and hydraulic systems. That meant the prop reacted slower to power changes. For those who are completely lost, the RPM control changes the pitch of the prop to maintain, or at least attempt to maintain, the set RPM. This doesn't mean that you can be idling and have the RPMs running at 3,000, after all the prop and engine are directly connected. A high RPM setting at idle simply means that the prop's pitch is the lowest allowed by its stops. Anyways, that fictional write-up at the beginning was done by someone who knows jack about aircraft systems and real flying.

There is currently a game in early beta that will destroy these games with realism. That game is the new IL-2: Battle for Stalingrad. I'd like to see us go there when that happens.
